I have released WMP Tag Plus, a Windows Media Player plug-in for viewing and editing metadata tags of MPEG4, Vorbis, FLAC and WavPack files.

WMP Tag Plus is different from the existing tag support plug-ins in the fact that it has a deeper integration into WMP, while the other plug-ins rely more or less on a workaround. This means that you can now use the Advanced Tag Editor to edit the tags of MPEG4, Vorbis, FLAC and WavPack files, which wasn't possible with the existing plug-ins. Another advantage is that WMP Tag Plus can set the playback length of these files in the library, which makes seeking possible when playing them.

October 22, 2009: WMP Tag Plus is now officially released, only some minor issues had to be fixed since the release of the second beta. The official WMP Tag Plus web page is at http://bmproductions.fixnum.org/wmptagplus

November 7, 2009: WMP Tag Plus 1.1 fixes a bug that prevented tag changes from being written correctly to certain FLAC files. This update is recommended if you are using the FLAC tag support of WMP Tag Plus.

How do I avoid WMP Tag Plus from adding mp4 music videos to "Video" library, as I prefer to view MP4 with audio tags such as used in "Music" library.

I've set up the Vista registry for Window Media Player to recognize mp4 as audio file, not video. [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Multimedia\WMPlayer\Extensions\.mp4]"PerceivedType"="audio"[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer\MLS\Extensions]"mp4"="audio"

You say music videos, so these MP4 files also contain a video stream and not only an audio stream? WMP Tag Plus will detect a video stream and report this to WMP, so I guess that's why WMP classifies it as Video.

You could try changing the extension of the files to M4A. I doubt that this will help (as M4A files are probably handled identically to MP4), but it's still worth a try.

Yes the MP4s contain video and audio. When I try changing the extension to M4a, they get added to the "Video" library with WMP Tags Plus enabled (which does not have audio tags editing in WMP). Without WMP Tags Plus enabled M4a are added to "Music Library" (with audio tags). This behaves the same as MP4, probably because WMP Tags Plus has same definition (MPEG4) for M4A and MP4.

What I need is an option for WMP Tags Plus to edit the IDE (MP3) tags inside the MP4s without causing WMP to add them to Video library. If I enable WMP Tag plus after adding MP4s to Music Library, it edits just fine.

If I define MP4 as FLAC in MWP Tag Plus it seems to add them to Music Library fien, and allow editing but tag structure is wrong.

Exactly, setting MP4 to FLAC is incorrect and won't work. MPEG4 is the only correct format.

I hope you can understand that I really don't like adding options to WMP Tag Plus for edge cases like this, options that most other users don't need and can only confuse them.

Note that you can edit tags of MP4 files in the Video library, and that they will be written to the files. It's just the Advanced Tag Editor that isn't available there. The Actors-field is equivalent to the Artist-field in Music.

If you really want to have them in Music, I see 2 possible workarounds:

- Make sure WMP Tag Plus is disabled while the files are added, and re-enable the plug-in afterwards.- Extract the audio streams to separate AAC files with a tool like YAMB. AAC files will be added to Music.

Thanks for you prompt feedback.

I'll work with first work-around option.

I hope you will consider in the future MP4 music videos for add in, as I would expect a lot more use since Youtube is now supporting HD downloads in MP4 format.
